Some years ago. I learned about a new -ish technology that fascinated me. I started to research ways to get in on the development of this technology: i.e. what sort of opportunities might there be for a startup or small business in the space.
The answer I found was very sobering and mildly depressing. There was no room for developing the technology itself. That had already been done by large companies with the capital and resources to commoditize things early.
Instead, the real opportunities were found in business/management consulting selling the product and tangential things, like having a construction company to help build out infrastructure needed for the technology.
At this point I think technology no longer interests me because it doesn’t have a place for me.
